I have been using LG 22MP68VQ for quite sometime and I must say I am pretty much satisfied with it. It has that infinity edge kind of display with very thin bezels so it has a modern feel to it when you see your code on it. Sharp and crisp images are its specialty and 22'' is more than you can ask for.
22" is to small for my taste. 24" is a minimum, and then at least in 16:10.
